i lived in the USA for 20 years, i think i know my way around
the more i think about it, the more i think cargo van is the way to go
here's a nice example

but on the wrong coast for me but still
we could be comfortable living in that for 6 months with something like this on the back

and this for a toilet

and i think easy to sell at the end of the trip or if we get bored half way through, we just make a sprint for NY, sell and go home
